Portable Power and Transportation Energy
March 12, 2021

A portable source that delivers 2 kilowatts continuously for one year would change the economics and architecture of electric transportation. Brian Greenforest set a target price of $400 and compared its annual energy to roughly 1.5 million fully charged iPhone 11 Pro batteries.

Eighty such modules would fit the power class of a 200-horsepower truck, turning one hard invention into a modular transportation platform.

Solve Energy Density at the Vehicle

Battery vehicles move energy through mines, factories, packs, chargers, transmission networks, and generation sites before the wheels turn. A year-long onboard source would collapse much of that infrastructure into a replaceable or refuelable product.

Brian’s 2021 analysis contrasted this target with a photovoltaic and lithium-ion conversion program whose infrastructure cost he estimated at $180 trillion, equivalent to 55 years of the 2020 transportation budget.

Open Every Serious Physical Path

Hydrogen fuel cells, efficient turbines, advanced nuclear systems, fusion, and other compact sources all deserve attention when the requirement combines continuous output, small size, safety, and low lifecycle cost.

Energy researchers and builders can use the 2-kilowatt module as a concrete design brief. Show the mechanism, calculate its mass and volume, and collaborate on the vehicle system that can carry it.

A unicorn inventor? Invent a portable $400-cheap 2 kilowatts continuous power source lasting one year without recharge. (It's an equivalent of 1.5 million fully charged iPhone 11 Pro Li-Ion batteries) You can bump up the price, if you can invent something more expensive, but still portable and providing 2 kW of electric energy. If you do that, the world will switch to electric cars. If you won't, we have to spend 55 years worth of the 2020 transportation budget ($180T) to convert all gasoline- and Diesel-fuel-powered cars and semi-trucks into Li-Ion battery powered, recharged using photovoltaic (PV) solar panels installed in each small town (1 square mile) to large cities (16 square miles). The alternative to find THAT MUCH money for Li-Ion PV solar "economy" is ridiculous and not feasible. We MUST THINK REALLY HARD RIGHT NOW, IMMEDIATELY, to invent a portable 2 kilowatts power source. 80 of such sources must fit into an average size 200 hp truck. So be careful with the size too. Fusion? Nuclear? WE DO NOT EVEN HAVE THEORETICAL OPTIONS for the most important problem the humanity HAS TO solve RIGHT NOW! We thought nuclear and fusion were jokes, or research projects, but NOBODY still can clearly tell you if these can, even in THEORY, replace gasoline and Diesel fuel.

Global transportation budget is $3.3T annualy, if you buy gasoline at your local gas station in WA, USA.

Let's plan to do this ASAP then. The humanity doesn't have time to wait until we focus on solving the RIGHT problem. 1. Silly how centralized electricity generation has occupied minds of so many inventors who fail to realize the cost of NEW wires for energy distribution, especially, a low loss superconducting wires in a superinulator coating. It all comes at cost $$$. With the existing electricity distribution systems, for heating purposes, people have zero reasons to switch from natural gas. 2. Silly how people who believe in electric cars, semi-trucks, drones, airplanes think that these can replace things we have at use (gas, piston, jet). Li-Ion battery is both expensive and heavy (at the same time!) Gasoline is a perfect energy storage, and will stay that way for many many decades. An attempt to fix that with compressed hydrogen and fuel cells is the most promising! While being super expensive as an "installation cost", it provides a premium weight per joule. And here we come to the...

3. Cost of recharging a battery. If Li-Ion for VEHICLES is a total crap, and hydrogen is so awesome, why can't we have it? Because it's TOO EXPENSIVE to split the water LOCALLY: sun doesn't shine everywhere! I genuinely believe that the best tool is a weather balloon covered with solar panels which compresses that hydrogen, and can be owned by households or small town districts. But I need help to understand how Archimedes, The First, and The Second Laws of Thermodynamics can be all happy with this crazy idea.

That's why it's so urgent and important to solve it RIGHT NOW. Otherwise people continue to burn natural gas to stay warm. INVENT!

Funny, the first thing I see to check if IndieGogo still offers a lifetime forever funding program... https://www.indiegogo.com/projects/elechive-portable-universal-super-power-station
